McKay quivers and Lusztig algebras of some finite groups

Ragnar-Olaf Buchweitz, Eleonore Faber, Colin Ingalls +1

We are interested in the McKay quiver and skew group rings , where is a finite subgroup of , where is a finite dimensional vector space over a f…

The magic square of reflections and rotations

Ragnar-Olaf Buchweitz, Eleonore Faber, Colin Ingalls

We show how Coxeter's work implies a bijection between complex reflection groups of rank two and real reflection groups in . We also consider this magic square of reflections…

Tilting theory for Gorenstein rings in dimension one

Ragnar-Olaf Buchweitz, Osamu Iyama, Kota Yamaura

For a -graded Gorenstein ring , we study the stable category of -graded maximal Cohen-Macaulay -modules, which is canonically triangle equivalent to the singula…

A McKay correspondence for reflection groups

Ragnar-Olaf Buchweitz, Eleonore Faber, Colin Ingalls

We construct a noncommutative desingularization of the discriminant of a finite reflection group as a quotient of the skew group ring . If is generated by order two…

Noncommutative resolutions of discriminants

Ragnar-Olaf Buchweitz, Eleonore Faber, Colin Ingalls

We give an introduction to the McKay correspondence and its connection to quotients of by finite reflection groups. This yields a natural construction of noncommutat…

Moore Matrices and Ulrich Bundles on an Elliptic Curve

Ragnar-Olaf Buchweitz, Alexander Pavlov

We give normal forms of determinantal representations of a smooth projective plane cubic in terms of Moore matrices. Building on this, we exhibit matrix factorizations for all inde…
